Let us not soil our minds with an ill-thought vengeance so that the innocent tenants of Islamic belief and the modern world are scuttled back into the barbaric mist of the middle ages.
Let us put the blame squarely where it belongs on the wretched souls and their leadership who planned and slaughtered the innocent in the name of God in France and in so doing blasphemed against a loving God of many names. One cannot kill in the name of a loving God, one only kills in the delusion of martyrdom that leaves the soul empty of what it longs for.
Let us also not exonerate the collective self, the peaceful people of the earth who live and let live in the toil of struggle and in the grace of being. We, Christians, Muslims, Jews, Buddhists, Sikhs and all other beliefs have allowed the radicalization of our young to become the stench of “looking the other way.” Moderate Islam needs to decry and destroy the radicals who have usurped the Prophet's words to their own end.
The litany of atrocities committed throughout history, via wars, crusades, conflicts and by individual radical actions in all beliefs have paved the way to the hell we now experience in the world. No one belief is exempt from contemptible acts of violence.
To the radical jihadists of murder, death and destruction you offend the peaceful tenants of The Prophet Mohammed. Mend your ways and mind your backs for the peaceful and the gentle mettle of civilized humankind is now poised to destroy you in ways you will never imagine.
